I have a dragonborn paladin in a game that's been going for a while now. He's got an 8 dex and wears (semi-spiky) platemail, with no stealth proficiency. If passive stealth were a thing, he'd have a 4. He also has the Far Traveler background from SCAG, which grants the background feature "all eyes on me." (People notice you and are curious about you.) So beyond being shiny and noisy, he's different-looking enough that people pay extra attention.
Later on, he got an artifact shield. One of the random negative properties rolled was "you emit a foul stench." We tweaked that to "you emit a strong, distinct, but not necessarily unpleasant odor" (since it was a king's shield).
So - like a box of lemons all got peeled at once, and the densest, most stuffy-nosed person you've ever met would still smell him as soon as he walked in the room.
(Do not lick the dragonborn paladin king. The flavor explosion might kill you.)
